2018 BMW 3-Series vs. Its Competition

2018 BMW 3-Series
Aaron Cole Aaron Cole Managing Editor

The BMW 3-Series is locked in a perennial struggle with Mercedes-Benz’s C-Class—and we dare say it’s losing.

The BMW has one ace in the hole: a rear-drive 340i with a manual transmission should be on every enthusiast shopper’s short list to drive.

The Audi A4 is more technologically advanced, with standard all-wheel drive, but we like the 330i’s turbo-4 more.

The Cadillac ATS is enthusiastic, if not somewhat rougher around the corners.

The Lexus IS and Infiniti Q50 are also-rans in the category for now, mostly hamstrung by finicky infotainment systems or lackluster performance across the board.

Quick Specs
6.7
The 2018 BMW 3-Series makes its strongest case in performance for luxury compact buyers’ attentions.
8.0
The 2018 Audi S4 balances perfectly performance with luxury in a package that's both practical and sharp. Hardly a recipe for excitement, but one that touches all the bases.
6.8
A sports car with a more practical body, the 2018 Cadillac ATS-V represents American engineering at its very best.
7.0
The 2018 Infiniti Q50 is powerful, well-equipped luxury sedan that doesn't quite match up to Germany's finest yet.
6.7
The Lexus IS needs more powertrain guts, and more styling glory, to tackle the cars it wants to take down.
7.5
Very expensive and still not very large, the 2018 Mercedes-Benz C-Class nonetheless leads its luxury niche with fabulous style and fantastic power and grip.
